Internally powered with a high-resolution 150 watt switching amplifier the Feature allows an unprecedented level of system connection flexibility. A standard RCA line-level input minimizes wire clutter by connecting directly to on-wall televisions (and other devices) without the need for external amplifiers.

Additionally, standard speaker-level connections allow the fully powered Feature to integrate with audio systems where RCA connection is not possible. Consumers choosing to use the Feature with a traditional receiver will experience an enhanced sonic experience without the need to upgrade to a more expensive model. Additionally, if consumers want the added benefit of RCA line-level connection and have a receiver equiped with pre-amp outputs, they can bypass the inferior amplification of an entry level receiver and instead utilize the Feature's superb internal amp.

A highly-sophisticated Vojtko™ crossover seamlessly blends the Feature's state-of-the-art electrostatic transducer, neodymium soft-dome tweeter, dual low-distortion 5.25-inch woofers, and 150 watt amplifier to provide crisp, clear, MartinLogan sound across the entire frequency range.

For those seeking an ultimate performance, clutter-free home theater experience Feature perfectly matches MartinLogan's fully powered Purity floor standing electrostatic loudspeaker and full line of low-distortion subwoofers.

Ultimate Performance RCA Connection

To achieve ultimate performance with the Feature use of the RCA line level connection is recommended. With this input Feature is able to connect directly to devices with variable level control such as digital music players, flat screen televisions, computers, or receivers with pre-amp outputs. Additional speaker level inputs also allow Feature to connect using traditional speaker cable in a system where RCA connection is not possible.

Internal 150-Watt High-Resolution Switching Amplifier

Internally powered with a high-resolution 150-watt switching amplifier, Feature allows an unprecedented level of system connection flexibility. This amplifier makes it possible for Feature to connect directly to devices with variable level control such as digital media players, televisions, or computers.

Hybrid Dynamic Technology

What really sets the Feature apart is a high-resolution neodymium soft dome tweeter embedded directly in the electrostatic panel. By eliminating the need for a bulky tweeter-housing mounted in front of the ESL panel (as found on the Cinema and Theater center channels), the Feature all but eliminates high-frequency diffraction. This unique mounting system also increases mid-range/high-frequency phase coherence and time alignment while offering superior dispersion characteristics (compared to previous MartinLogan center channels).

CLS™ Generation 2 Electrostatic Panel

Innovative manufacturing techniques enabled MartinLogan to produce the original Curvilinear Line Source panels, the first wide-range electrostatic drivers to deliver good horizontal sound dispersion without sacrificing overall sound quality or reliability. CLS Generation 2 builds on that success with advanced diaphragm and stator technologies that significantly enhance speaker efficiency and dynamics.

Our new thin-film plasma-deposition process applies an improved conductive coating to the ultra-low-mass PET (polyethylene terathylate) diaphragm for superior adhesion and abrasion resistance, as well as a better impedance characteristic. MicroPerf stators expose more of the diaphragm surface, dramatically expanding effective radiating area without increasing panel size, while ClearSpar™ spacers help maintain their stiffness without impairing the signature transparent look of MartinLogan electrostats.

Curvilinear Line Source Electrostatic Panel

One of MartinLogan's original breakthroughs, CLS™ technology has been an essential ingredient of every electrostatic loudspeaker we've produced. Proprietary manufacturing methods enable construction of electrostatic panels as cylindrical sections. Their gentle horizontal curvature solves the problem of obtaining good high-frequency dispersion from a large radiating surface without compromising overall sound quality or reliability.

MicroPerf Stators

Although stators are the elements of an electrostatic driver that are supposed to stand still, they carry the audio signals that do the work of propelling the diaphragm back and forth to move air and produce sound. Because the stators sandwich the diaphragm between them, they must be perforated to allow sound to pass through. Yet they must also be rigid enough to remain absolutely stationary despite the strong electrostatic forces pushing and pulling at them during operation.

MartinLogan's MicroPerf design optimizes this tradeoff by reducing the size of the individual holes and using many more of them than in a traditional electrostatic panel. MicroPerf almost doubles effective diaphragm radiating area without compromising structural integrity. The resulting increase in output capability and efficiency allows a panel to be made much smaller without sacrificing performance – or to enjoy a substantial leap in bandwidth and dynamics without growing larger.

Low-Distortion Woofers

By eliminating cone flexure, Feature's rigid paper-cone diaphragms help our advanced-technology woofers achieve the very low distortion necessary for proper blending with MartinLogan electrostatic panels.

On-Wall/Off-Wall Acoustic Contour Switch

Feature features a unique 'on-wall/off-wall' switch that tailors acoustic equalization to either installation option. Simply set this switch to On-Wall if mounting to a surface. Set the switch to Off-Wall if the Feature is more than four inches from a wall. Setting this switch ensures that you will achieve total system matching in even the most diverse setups (such as systems mixing on-wall and off-wall installations).

Vojtko™ Crossover

Carefully hand-built using only the finest polypropylene capacitors and air-core coils, the crossover employ's MartinLogan's proprietary Vojtko topology for vanishingly low distortion and seamless driver integration. This precision-tuned network preserves even the most microscopic sonic nuances while handling the full dynamics of any source.

Application Versatility

Feature is suitable for use in any stereo or multi-channel audio system, mounted either on- or off-wall. And it blends well with other MartinLogan speakers in both sound and appearance, which allows mixing and matching to meet specific installation requirements.

Installation Versatility

The Feature LCR speaker easily installs on a set-top or shelf. Additionally, using the included wall-mount brackets and installation template Feature may horizontally/vertically mounted to a wall (under or beside a plasma screen, for example).
